Leak Saver Foam Blaster AC Coil Cleaner Foam Spray | HVAC Coil Cleaner for AC Unit | Professional Deep-Penetrating Formula for Evaporator (No Rinse) & Condenser (Light Rinse) - 3 Pack

If you want to clean your window air conditioner without taking it out of the window this stuff is great. It doesn't need to be rinsed off of the evaporator coils (the ones on the inside), so you can just spray it on and then turn on the air conditioner when it's finished. It shoots a very tight spray to get in between the coils and then foams up. It has a nice citrus smell and it will take away musty odors coming from your a/c. It will also work on the condenser (outdoor) coils but it has to be rinsed off with water. Do this once or twice a year to keep your air conditioner clean and smelling fresh.

I've been using this product on my Mom's indoor HVAC unit that has been badly neglected for many years. There is literally a compacted dirt cake around the coils underneath the fins. Standard foam spray does little to help, but makes the exterior "look" clean. This spray is more heavy duty and precise. With delayed foaming action, it allows the foam to reach the deeply embedded dirt. Still, on a system that hasn't been cleaned in a severely long time, even the best products struggle. I've used all three cans, and every time more dirt flakes work themselves out of the fins. The problem is that any remaining dirt migrates over time, gets stuck again in a different area, and causes dripping of water that falls onto the filter itself. I'm planning on buying another set of this brand. My best advice for a badly fouled indoor coil is to spray from both sides of the fins, top side and bottom side, use a soft paint brush the gently brush out the dirt flakes, use a properly sized fin comb to reach into hard to reach corner spots and smooth out any damaged fins, follow with a light rinse using a spray bottle, distilled water is preferable but not absolutely necessary. If I do buy another set of cans, I will update my review and let everyone know the results. This product is so far the best one I've used, is easy to use, and probably highly effective for an average dirty HVAC coil. For a compacted dirt cake like mine, be prepared to be persistent, multiple cleanings will be necessary to break all that dirt free.

I bought the 3 pack, I saw a lot of videos, pros and cons, I pulled the trigger and bought it! it worked! all of the dirt grim came off like better, I do recommend this product! the smell is clean, not even strong scents that lingers. It foams up really thick and full. I totally recommend this product!

Cleans good only thing that would make it better is if its smell wasn't as strong. Maybe it was just that I used the entire can in a window unit. Would buy again

Very easy to use, good foaming action. My coils were not as dirty as I thought even after 10+ years of never being cleaned but the water runoff was still dark. Consider 2-3 cans for 2 row condenser and indoor evap cleaning as one can barely covered my single row condenser and indoor evap coils. Pleasant scent but consider ventilation or respirator for indoor evap cleaning. Great product, will use again for future coil cleaning.

Watched a few videos before making this purchase. The day of cleaning, I removed the top of the ac unit along with the side covers. Lightly vacuumed the coils and bottom and then sprayed the inner and outer coils with the cleaner. It didn't seem to spray out and foam as much as what I watched in the videos but it did appear to work at getting the grime to the surface. Afterwards (15 min), I hosed off the coils several times and they looked pretty clean. Overall I'm satisfied with this product, the citrus scent was not overwhelming and I went through 3 full cans to do my 3 1/2 ton condenser.

This stuff works so well. I was cleaning my moms air conditioner and she has had it for over 5 years never cleaned it. This stuff did eberything it says it would do. I did what the directions said to do and it started working in 5 minutes. When I tell you that foam took all the dirt off it literally did. It was eating away at it and it was melting off.

Works great very easy to use in this Can removes very easy on the fins well made product.

Super efficace et facile à utiliser

Worked well followed the instructions for once and it did what it said it was going to do dissolve the dirt and then I just sprayed it off.

Not much to say about this product. It’s does its job, sprayed the entire can onto my AC fins without difficulty. Just so much easier buying online here than walking through HomeDepot and end up buying others things I don’t need.

Bad canister

As advertised. Good product. Got the smell out of the car AC condenser.
